4. Subheading 480512 covers paper, in rolls, made mainly of straw pulp obtained by a combination of mechanical and chemical pulping processes, weighing 130 g/m2 or more, and having a CMT 30 (Corrugated Medium Test with 30 minutes of conditioning) crush resistance exceeding 1,4 newtons/g/m2 at 50 % relative humidity, at 23 °C.
5. Subheadings 480524 and 480525 cover paper and paperboard made wholly or mainly of pulp of recovered (waste and scrap) paper or paperboard. Testliner may also have a surface layer of dyed paper or of paper made of bleached or unbleached non-recovered pulp. These products have a Mullen burst index of not less than 2 kPa·m2/g.
6. For the purposes of subheading 480530, ‘sulphite wrapping paper’ means machine-glazed paper, of which more than 40 % by weight of the total fibre content consists of wood fibres obtained by the chemical sulphite process, having an ash content not exceeding 8 % and having a Mullen burst index of not less than 1,47 kPa·m2/g.
7. For the purposes of subheading 481022, ‘lightweight coated paper’ means paper, coated on both sides, of a total weight not exceeding 72 g/m2, with a coating weight not exceeding 15 g/m2 per side, on a base of which not less than 50 % by weight of the total fibre content consists of wood fibres obtained by a mechanical process.
